Title: Thermal infrared type solid-state image sensor
Inventor: TSUKAMOTO NANAO
IPC: H01L35/32
Filed: 1994-03-30
Abstract: PURPOSE:To detect accurately a bias charge component of a thermal infrared type solid-type image sensor and improve thermal responsibility of a temperature detection element. CONSTITUTION:A component of a region that a bias charge component excluding a signal component is detected to be a reference level is not structured with a diaphragm configuration without being provided with an etching hole 21, and packed with a polysilicon 24. Accordingly, an infrared-ray-shielding film is not required to be provided in a reference level detection region 100S, and as there is no difference between the reference level detection region 100S and an image region 100 in a stabilizing process in a manufacturing process, a precise reference level can be obtained. Also, a thickness on the diaphragm (two-layer film of 14, 15) can be thinned to improve thermal responsibility.

Title: Planetary reduction gear build-in type starter
Inventor: UKITA KAZUHIKO
IPC: F02N15/02
Filed: 1986-03-18
Abstract: PURPOSE:To enable sufficient buffering effect to be developed even if a large impact force is applied, by interlocking an engaging member that can convert the torque caused by the rotational fluctuation applied on an internal gear into a force in the axial direction. CONSTITUTION:The torque produced on the rotating shaft 11 of a d.c. motor 1 is transmitted to a planetary gear 8 via a spur gear 12, and by the planetary gear motion thereof it is transmitted to an output turning shaft 15. When a torque caused by the rotational fluctuation is produced on an internal gear 18 which transmits the reaction force of the output turning shaft 15 caused by the planetary gear motion to a machine frame 21, an impact force is applied on a pressure receiving part 19 arranged on the internal gear 18. Thereupon, while the impact force is applied on an engaging member 20 interlocked with the pressure receiving part 19, since the axial direction projected parts 20b are fitted in the cutout parts 21a on the machine frame 21, the movement of engaging member 20 in the diametrical direction is restricted, and the contacting part 20a moves in the axial direction keeping contact with the slopes of projections or recesses of the pressure receiving part 19. Thus, the engaging member 20 converts the impact force into a force in the axial direction.

IPC: H01L21/822
Filed: 1980-05-13
Abstract: PURPOSE:To reduce the current in the stand-by mode without deterlorating the characteristic in the active mode by changing the self-bias voltage based on the active mode and stand-by mode. CONSTITUTION:When a chip enable signal CE supplied to an input terminal 2-1 indicates the active mode, only a self-subbias generator 2-2 is operated and bias voltage VB outputted to an output terminal 2-5 becomes approximately -2.5V. The voltage VB is supplied to terminals 3-1-3-3 of an inverter circuit, causing a transistor TR T6 to be conductive and an input signal at an input terminal 3-4 is inverted to appear at an output terminal 3-6. When the signal CE then changes to the stand-by mode, only a self-subbias generator 2-4 is operated and the voltage VB becomes -5V. As the result, TR T6 is completely out off and power consumption is reduced. Further, since oscillating frequency also may well to reduce to 1/10-1/100, the power consumption of the generator 2-4 can also be 1/10-1/100.
